So what if you think that you have a leaking injector on your Peugeot 1007? You likely figured it out thanks to black/oily drips along your engine, or a disturbed idle, or uncommon black smoke. These three signs of illness are the main signs of a leaking injector. As this failure can bring about more serious engine problems on your car, we decided to prepare this content to help you confirm the failure of a leaking injector and deal with it correctly. To accomplish this, we will initially look at the circumstance of gasoline injectors and then at those of diesel injectors Peugeot 1007.
Leaking injector on my petrol Peugeot 1007
It is vital to know that the injectors on petrol and diesel engines are different, actually, the difference in combustion between these two types of engines makes the injection different. The key difference lies in the pressure experienced by the injectors, on a petrol engine it will vary between 3.5 bars for indirect injection and 120 bars for indirect injection.
Leaking injector on a petrol Peugeot 1007: The different leaks
It should be mentioned that injector leaks on a Peugeot 1007 equipped with a petrol engine are rather rare. This is resulting from the much lower pressure in the petrol intake systems. Nevertheless, there are two types of leaks:
- Leakage from the top of the injector:
It is possible that you have a leak from the top of the injector, this is the part that is attached to the fuel rail, an O-ring will be involved in this. - Leak injector of the lower part:
At last, you may suffer a leak coming from the lower portion of the injector of your car, this one will come from the junction with the engine and not with the rail as seen before.
Leaking injector on my diesel Peugeot 1007
Unlike petrol engines, which have spark combustion, diesel engines run on compression. This combustion procedure produces very high pressure in the engine, as do the injectors. On these models, the pressure is more than 10 times higher than on the direct injection of car petrol engines, reaching 1800 to 2000 bars.
Leaking injector on diesel Peugeot 1007: The different leaks
In the circumstance of leaking diesel injectors on your Peugeot 1007, there are three several types of leaks:
- Leakage from the injector inlet:
In this instance, it is an inlet pipe that will deform after a while, commonly the leak will be at the clamping point. - Injector return leakage:
As its name reveals, this leakage relates to the management of the fuel return in the injector, this time the injector that leaks on your Peugeot 1007 will be a consequence of an O-ring or its plastic tip that leaks. - Injector base leak:
This injection leak is one of the most annoying, it is the junction between the engine and the injector nose that leaks at a copper seal, you should encounter an air noise and a compression loss. - If after checking you have oil leaking but it does not come from your injectors, we suggest you to browse this content on the presence of oil leaking on your Peugeot 1007.
Leaking injector on my Peugeot 1007, how to fix the leak
And finally, we’re going to look at how to fix a leaking injector on your car. Frequently a leak is associated, as we have seen prior to this, to a worn seal because of the pressures suffered. But think that the pressure in the circuit is tremendous, especially on diesel engines. So you will have to take some safety measures:
- Lower the pressure before any work is conducted…
- Masking you to avoid the risk of fuel spillage
- NEVER work on a running diesel engine injector.
Concerning the repair part of your leak, it will very often be restricted to changing the seals that have failed:
- Locate the source of the leak
- Take apart the injector in question
- Change the corresponding seal kit
- Reassemble the set up and tighten with a torque wrench in respect with the manufacturer’s standards.
In all situations, these interventions are not specifically complicated, but if you have the tiniest hesitation in the treatment of your injector that leaks on your Peugeot 1007, we suggest you to get closer to your motor mechanic to avoid any bad manipulation that could critically harm the condition of your Peugeot 1007.
